Definitions

  • the efliciency of the vibrational and acoustieal suppression in the assembly is primarily a function of the resilience of the rubber which in turn is determined by its composition 'and thickness.
  • Other advantages are also to be found in resilient 'axle box mountings. 'No loosely-'fitting parts are incorporated to promite noise and increased wear.
  • This objective is accomplished by providing a rubber bushing formed of a plurality of arcuate segmeuts which provide varying resilience :and darnping at diametrically opposed areas of the bushing.
  • Another object of this invention is generally to improve the performance and endurance of resiliently mounted axle 'bearing assembles.
  • PIG. 1 is a view in elevation of one embodiment of' the resilient bearing .assemb1y, shown partially in cross section;
  • FIG. 2 is a cross-sectional view of the bearing assembly of FIG. 1 taken along the line 2-2, illustrating particul'arly the split housing and split resilient bushing;
  • IPIG. 3 is a view similar to FIG. 2 illustnating a second embodiment of this invention, the housing in this case being split at an angle with respect to the horizontal.
  • this invention comprises a split bearing housing including upper .and lower housing sections 2 and 4, respectively.
  • a resilient bushing 6, which prefera'bly includes an upper segment 8 and a lower segment 1, is closely fitted in the circular opening provided in the bearing housing and is circumferentially supported thereby.
  • the bushing is formed with a trough 12 in its outer surface into which mating surfaces of the respective housing Sections are positioned, the Sections completely filling the trough formed in the bushing.
  • the upstanding sides 14 and 16 of the bushing labut the edges of the respective housing sections to maintain the bushing in a fixed ax'ial position with respect to -the housing.
  • the circumferential relieved portions 17 and 1-9' provided in the outer surface of the resilient bushing provide void space into which the bushing flows ⁇ during deformation.
  • a metal bearing-retention member or liner 18 is provided around the internal periphery of the resilient bushing, providing internal support to the bushing and a firm seat in which a bearing 20 is retained.
  • a channel provided in the outer surface of the liner 18 conforms closely to the shape and size of the contained lbushing and the bushing is held captive between the liner and the opposing housing sections. It will be seen that within the lmits established by the resilience of the bushing in an axial direction the liner is relatively mmovable in the assembly in such direction.
  • An internal annular shoulder 22 is provided in the interior surface of the liner 18 to form a seat against which the bearing 20 is axially positioned.
  • the liner may optionally be proyided with an internal passageway through which lubrication may be furnished to the bearing.
  • the lubricating material would be fed to a peripheral channel 24 formed in the inner surface of the liner and then to the bearing through a conduit (not shown) drilled through
  • the liner will be closely fitted onto the bearing and accordingly the liner will be of sufficient thickness to provide the requisite circumferential support for the bearing to maintain the fit, and thus hold the bearing in a fixed position with respect to the liner.
  • the bushing is formed into a plurality of arcuate segments to provide varying resilience at diametrically opposed areas of the bushing.
  • the bushing is formed into two segments 8 and 10 which are held against circumferential rotation by flange portions 30, 30a, 32 and 32a which engage in a cooperating recess provided in the housing.
  • One of these segments is formed of a material having different vibration damping characteristics than those of the other section whereby any oscillations set up by the resilience of one segment is opposed by the different natural frequency or absolute damping effect imposed by the other section.
  • one of the segments will be 'formed of butyl rubber which is known to exhibit excellent vibration damping qualities.
  • the normal vibrational forces generated at the bearing will include both a Vertical component resulting from wheel unbalance and track irregularites, and a horizontal component resulting from varying wheel drag, it may be preferable to orient the axis of the division between the bushing segments at an angle with respect to the horizontal. Such an orientation is shown in FIG. 3. Although in the drawings the direction of the split in the housing has been shown to coincide with that of the split in the bushing, this is, of course7 not necessary, although it will normally be the most convenient construction. Further, although the bushing has been illustrated and described to show the bushing formed in semi-circular segments, it may be advisable in a given installation to form the segments in a different configuration; or to provide a different number of segments or segments of different thicknesses.
  • Al resiliently mounted axle bearing assembly comprising:
  • a split housing including upper and lower housing sections defining a circular opening parallel to the axis of the assembly
  • a metal bearing-retention member having a channel formed in its outer surface
  • a resilient bushing held captive in the channel of the metal member and sandwiched in the circular opening between the metal member and the housing, the bushing having a trough formed in its outer surface into which cooperating surfaces on the respective housing sections are closely-fitted, the bushing being split into upper and lower arcuate segments of different materials to provide different vibration-damping characteristics at diametrically Opposed areas of the bushing, and
  • axle bearing assembly of claim 1 in which one of the segments of the resilient bushing is fabricated of butyl rubber.
  • a resiliently mounted axle bearing assembly comprising:
  • a split bearing housing including upper and lower housing Sections defining an opening parallel to the axis of the assembly
  • a captive annular resilient bushing positioned within the opening and circumferentially and axially supported by the housing, the bushing being formed of a plurality of arcuate segments of materials having a different modulus of resilience at diametricallyopposed areas of the bushing to provide inherent oscillation damping,
  • a resiliently mounted axle bearing assembly comprising:
  • a split bearing housing including upper and lower housing sections defining an opening parallel to the axis of the assembly
